Just as the burning chair ammeter I needed a favorable volume meter to measure the volume of the test systems and housing. Of course there are much better equipment, which then beat but neat in price. For my purposes, this unit goes here and I highly recommend it. The processing is cast. Quite well, the device is very compact and are meaningful values. While there is an average-button, but we value higher than the actually measured values upon actuation - too bad. A countdown to measure or equivalent would be great here.
Conclusion: Small, stylish, yet nimble! Exact values, a decimal point and the price of 20-23 (depending on the state). For small, quick measurements highly recommended!
